Effects of spring applications of dazomet on root diseases and performance of Douglas-fir and western white pine transplants, USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Tests were conducted at the USDA Forest Service Nursery, Coeur d'Alene, Idaho to evaluate effectiveness of spring fumigation with dazomet to improve survival and performance of Douglas-fir and western white pine transplants. Spring fumigation greatly reduced populations of potentially pathogenic Fusarium and Pythium spp. Disease levels of container (plug+1) and...

Effects of preplant soil treatments on Fusarium and Trichoderma populations and fungal root colonization of 2-0 nondiseased western white pine seedlings - USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Preplant soil treatments were implemented to determine effects on populations of potentiallypathogenic Fusarium and potentially disease-suppressive Trichoderma spp. as well as root colonization by these and other selected fungi on healthy-appearing, bare root 2-0 western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Soil treatments included...

Breeding for bruchid resistance in common bean (Phaseolus vulgaris L.) : interspecific introgression of lectin-like seed proteins from tepary bean (P. acutifolius A. Gray), genetic control and bruchid resistance characterization.

Creator:: Kusolwa, Paul Mbogo
Abstract:: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...

An evaluation of the efficacy of hot water-chemical treatments to clean styroblock containers, Champion Timberlands Nursery, Plains, Montana

Creator:: James, Robert L., Woollen, R. L., and United States. Forest Service. Northern Region
Abstract:: Treating styroblock containers in hot water (68°C) with a very dilute bleach and detergent solution effectively reduced populations of Fusarium and Cylindrocarpon spp., two potential root pathogens of containerized conifer seedlings. However, the treatment did not significantly reduce levels of Phoma (another potential pathogen) nor saprophytic Penicillium and Alternaria spp....

Fungal colonization of styroblock containers Plum Creek Nursery, Pablo, Montana

Creator:: James, Robert L. and Gilligan, Carma J.
Abstract:: An evaluation of the efficacy of steam treatment on reducing levels of Fusarium, Cylindrocarpon, and Trichoderma within styroblock containers was conducted at the Plum Creek Nursery in Pablo, Montana. Although levels, of both Fusarium and Cylindrocarpon were significantly reduced by cleaning, relatively high populations of both these fungi persisted after...

Fusarium root disease of western white pine seedlings at the Coeur d'Alene Nursery, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Root disease of 2-0 western white pine seedlings occurred at the Coeur d'Alene Nursery in 1982 within seedbeds fumigated with methyl bromide and chloropicrin. Although losses were not substantial, there were several groups of dead seedlings within affected seedbeds. Fusarium oxysporum was most often isolated from diseased roots. Other Fusarium...

Nursery conifer diseases : evaluation of Benomyl to control root disease of Engelmann spruce seedlings

Creator:: Williams, Ralph E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The benomyl fungicide, rersan, applied at 7 and 14 pounds active ingredient per acre, on April 26 and July 25, 1973, was ineffective in reducing mortality in 2-0 Engelmann spruce seedlings derived from two different seed sources growing in three different nursery sections at the USFS Coeur d'Alene Nursery. Percent...

The Biology and control of the septoria diseases of winter wheat in western Oregon

Creator:: DiLeone, Julie A., Coakley, Stella M., Karow, Russ, Mundt, Christopher C., and Oregon State University. Agricultural Experiment Station
Abstract:: The septoria diseases of winter wheat are a limiting factor to wheat production in the Willamette Valley. This publication will describe the symptoms and development of the septoria diseases, including the influence of environmental conditions, the reactions of different cultivars to Septoria, the impact of Septoria on yield, and control...

Pathogenic Fusarium on spruce seed from the Towner Nursery, North Dakota

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Five seedlots of Colorado blue spruce and three seedlots of Black Hills spruce were sampled for Fusarium contamination. All seedlots contained some seed and/or debris with Fusarium. Levels of contamination were greatly reduced by treating seed with running water rinses for 48 hours or with chemical sterilants such as sodium...

Control of the western pine shoot borer Eucosma sonomana Kearfott in selected ponderosa pine plantations in northern Idaho and western Montana

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and Sartwell, Charles
Abstract:: A synthetic pheromone of the western pine shoot borer, Eucosma sonomana Kearfott, has been used successfully as a 'mating disrupter in northern Idaho and western Montana since 1984. Infestation levels in treated ponderosa pine plantations declined from an average of 28 percent infested in 1983 to 5.5 percent by 1986....
